我正在尝试使用 querybuilder.js 构建一个页面，我将在其中构建一个表达式并将其转换为 JSON 规则。
下面是我的 app.js 文件
var valuesJson = [
{'operand1': 'operand1'},
{'operand2': 'operand2'},
{'operand3': 'operand3'}
];
var options = {
allow_empty: false,
operators: $.fn.queryBuilder.constructor.DEFAULTS.operators.concat([
{ type: '=', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['number', 'string'] },
{ type: '!=', optgroup: 'custom', nb_inputs: 2, multiple: false, apply_to: ['number', 'string'] },
{ type: '>', optgroup: 'custom', nb_inputs: 3, multiple: false, apply_to: ['number', 'string'] },
{ type: '<', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['number', 'string'] },
{ type: '>=', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['number', 'string'] },
{ type: '<=', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['number', 'string'] },
{ type: 'contains', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['string'] },
{ type: 'begins_with', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['string'] },
{ type: 'ends with', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['string'] },
{ type: 'before', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['string'] },
{ type: 'after', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['string'] },
{ type: 'between', optgroup: 'custom', nb_inputs: 1, multiple: false, apply_to: ['string'] }
]),
filters: [
{
id: 'operand1',
label: 'operand1',
icon: 'glyphicon glyphicon-globe',
type: 'string',
input: 'select',
//optgroup: 'core',
//placeholder: 'Select something',
values: valuesJson,
operators: ['equal', 'not_equal', 'is_null','=','between','before','after']
},
{
id: 'operand2',
label: 'operand2',
icon: 'glyphicon glyphicon-globe',
type: 'string',
input: 'select',
//optgroup: 'core',
//placeholder: 'Select something',
values: valuesJson,
operators: ['equal', 'not_equal', 'is_null','not_between']
}
]
};
$('#builder').queryBuilder(options);
$('.parse-json').on('click', function() {
console.log(JSON.stringify(
$('#builder').queryBuilder('getRules'),
undefined, 2
));
});
由于between运算符已经列在全局运算符中，因此它在过滤器中出现了两次。
我想摆脱全局运算符并仅从我定义的列表中选择运算符名称（即使它已经存在于全局运算符中）。
